Professional Applications & Engineering Value

These metric socket head cap screws engineered from polypropylene plastic solve critical challenges in industrial applications where metal fasteners cause galvanic corrosion or electrical interference. The M4 x 0.7mm coarse thread design prevents cross-threading in plastic components while maintaining Class 6g thread fit precision. The socket head configuration with 3mm hex drive allows for high-torque installation in confined spaces, making them ideal for mechanical assemblies in electronics enclosures, automotive components, and food processing equipment. Their 4500 psi tensile strength combined with temperature resistance from -20° to 180° F ensures long-term reliability in varying environmental conditions without compromising structural integrity.

Specification Summary & Compliance

This M4 socket head cap screw features precise Class 6g thread fit tolerance per ISO metric standards with 14mm length and 0.7mm coarse pitch threading. Manufactured to DIN 912 specifications for dimensional accuracy and socket head profile. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in regulated industries. The fully threaded design maintains consistent engagement while the standard hex drive accommodates universal installation tools.
